Loudoun County

1757 Colonial Farmland, Safe Haven for the U.S. Constitution & The Global Internet Hub

Loudoun County was created in 1757 from Fairfax County and named for John Campbell, 4th Earl of Loudoun, who served as Commander-in-Chief of British armed forces in North America during the French and Indian War. During the War of 1812, when British forces marched on Washington and burned the Capitol and White House, President James Madison fled to Loudoun County. State Department clerk Stephen Pleasonton evacuated the original Declaration of Independence and the United States Constitution to Leesburg, secretly hiding them in Rokeby House to preserve the foundational documents of the American republic.

For more than two centuries, Loudoun County was defined by its rolling agricultural hills, Quaker mill villages like historic Waterford, thoroughbred horse farms, and scenic views of the Blue Ridge Mountains. In the late 20th century, the opening of the Dulles Greenway, the arrival of America Online (AOL) headquarters, and the establishment of MAE-East (one of the original Internet backbone exchange points) triggered a revolutionary economic transformation. Today, eastern Loudoun County—known globally as "Data Center Alley"—processes the vast majority of the world's digital traffic, while western Loudoun preserves Virginia's premier horse and wine country.
